'Patented July '7, 1908.l

Application led July 2, 1907. Serial No. 381,823.

'l'o all whom fit may concern:

Be it known that I, J ACK C. MORGAN, a citizen ol` the United States,residing at Frankfort, in the county of Franklin and State of Kentucky, have invented new and useful Improvements in Fans, of which the followingy is a speciiioation. i

'lhis invention relates to fans, conteinplating particularly a hand fan having spring gearing adapted to be energized or rewound by a controlling device on the handle of the fan.

The primary object of the invention is to provide a fan of this character having a novel constructimi of spring propelling mechanism and rewinding means therefor, whereby the blades of the fan Amay be propelled a considerable period without rewinding.

A further object of the invention is to provide a fan having a novel brake device which may be set to sto or control the speed ol' the fan blades at wi l.

A still further object is to p rovide a fan in which the blades may be fol ed to allow the lan to be compactly stored and carried.

'Phe invention consists of the features of construction, combination and arrangement ol parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in whicli1- Figure l is a longitudinal section through the casing of the fan showing the remaining elements in side elevation. Fig. 2 is a sectional elevation taken at right angles to Fig. 1. Fig. 3 is a detail. section on line 3-3 of Fig. 2. Fig. 4 is a similar view on line 4 4 oi F ig'. 2.

Referring to the drawing, the numeral 1 represents the casing of the fan mechanism which ma)v be formed of sheet metal or other suitable material, and preferably tapers longitudinally toward its base, from which projects a handle section 2 open at one side for the convenient insertion of the parts of the inclosed gearing in 'assembling the elements of the fan and the removal of said parts in eifecting repairs. The open side of the handle is closed by a movable section 3, said section constituting an operating lever pivoted at its lower end to the body of the handle, as indicated at 4. The pin of the pivotal connection may be detachable so that the combined. lever and closure 3 may be conveniently removed when occasion requires. The upper end of the lever 4 projects upwardly into the casing in the form of a curved extension 5, which carries a rimary actuating device f or the propel in'g gearing of the fan mechanism, as hereinafter described, and secured to the body of the handle is a spring 6 which, inthe form shown,

is a curved plate spring bearing at its free end upon the lever normal position. Any other type of spring for this purpose 'may, however, be em- 3 to hold it out-pressed or in ployed. The extension' of the lever is adapted to abut against the casing to limit the outward movement of said lever under'. the-pressure ofthe spring.

Arranged at the upperl end of the casing is a fan shaft 7, which extends transversely across the casing and is 'ournaled inthe side Walls thereof, one end of said shaft being extended beyond the casing, as shownin Fig. 2. Fan blades 8, of Which'any suitable number may be employed, are mounted u on the extended end of the shaft and may e fixed or pivotally connected thereto as desired, In the present instance, each fan blade is shown as provided at its innerend with a collar or sleeve 9 loosely en aging the shaft and pivotally connecting t e blades thereto so that said blades may be folded in lapping relation and in a plane parallel with the casing, thus enabling'the fan as a whole to be folded or collapsed in close compass for convenience in storage or transportation or carrying the same in the pocket. A spacing sleeve l() is arranged on the shaft, against which the co1- lar on the inner fan blade bears, and the outer end of the shaft extension is threaded to receive the securing nut 11 by which the collars may be clamped in (position and vloosened for adjustment to fol the blades to collapsed position.

A pinion 12 is iixed on theshaft 7 within the casing 1 and is driven by a train of gears 13, including a primary pinion 14. Meshing with this pinion is a power transmitting gear 15 loosely mounted on a transverse shaft 16, on which is also loosely mounted a drive gear or pinion 17. lThe drive gear or inion 1 7 is adapted to be engaged and turne in a ooun ter-clockwise direction by a rack vbar 18 formed by one of the arms of a yoke 1.9.carried by the lever extension 5, the yoke operating to guide the upper end of the lever in its movements and maintain the rack bar in proper inion. By this means the use of an auxillary guide for the rack upon a frame or extension from the casing is avoided, and

position for engagement with the' 45 Y and upon its reverse movement will engage 50 of the springfmoftorl andratchet'mechanism that one movement of the lever `3 will Wind upthe spring to o erate the lfan be mounted l ride loosely over said teeth on lcoil spring to transmit in otion to the ratchet ygear 15, whic ran ement being'su'ch t hence all the aparts exclusive ofthe rack may irectly upon the casing.

'Fixed on the-shaft 16 alongside the. drive gear 17 is a ratchet wheel 20, whose teeth extend in a clockwisedirection and are adapted to be'engaged by-a paWl or-do 21 on the gear -17 whenathe latter is rotated orward and to or clockwise movement of said gear.

The shaft is adapted to be propelled by' a 22 'fixed at one end thereto and at its oplposite end tothe easing, as indicated `at 23, t us forming a spring motorfor the ear train.13. The gear 17 and ratchet whee 20 On the shaft 16 is also fixed a its teeth extending a'pawl .or do 25 on the power transmitting iis loose u on the shaft, the Aa-rat in the operation of t elever 3 motion will be communicated tothe gear 17 to wind up the spring, which will be permitted tosimultaneously operate Wheel 24 and thence to the gear 15 through the instrumentality of the dog 25 to drive the fan operatin gearing. l

Wientlie lever 3 is pressed inwardl by the action of the hand grasping the handle 2, .the raek`^`barf18 will mesh with 'the gear 17 and transfer counter-clockwise motion there- -to under-which the do 21 will en age turn the ratchet whee? 20 to u the spring 22. Upon the return `of the rac bar to normal position by the retraction of the lever 3 through the spring 6, the gear 17 will be rotated in the reversedirection and the pawl 21 Will slide directly overthe-teeth of the ratchet wheel 20. The spring in expandin will transfer motion to the shaft' 16 which will rotate the ratchet wheel 24 fixed thereto, which Wheel on' its counter-clockwise movement will turn without operating the dog25 the dog and transfer motion to the gear 15 by which the train 1'3 will be driven to rotate the fan shaft 7 and the blades carried thereby. The.form`,iproportion and arrangement may be such i blades for a considerable perio thus obviating the necessity of constantly manipulating `the lever.

In order to stop the gearing when desired andto control the speed of operation thereof, a brake shoe 26 is provided .to engage one of the gears of the train, said shoe being pivotally mounted upon the casing as indicated at 27. Pivotally connected at its up er end of the shoe is a rod 28, extending ownwa'rd into the handle 2 and carrying at its lower end a stem 29 movable `ina slot 30 in the hano'r button by which the rearward dle, said stem having an exterior linger piece it may be moved, longitudinally in one 'direction or the other in said slot to im art-corres onding motion to the rod, where y the bra e shoemay be Vthrown, into and out of action to entirel stop or control the s eed ofrotation of the gearing as desired. he convenienceofjthis part of a device will be manifest.

l' It will be understood, offcours/that the fan when used is held in the hand and the lever 3 vibrated at intervals to energize the motor, but the form of the handle 2 is such as to adapt it to be mounted upon a suitable constitute means'for winding up the spring to 1 energize the motor for action 1n driving the gearing. ratchet wheel 24,.having 1 in a counter-clockwise direction for engaging vsu ort for convenience of the operator.
